Jammer Grenade
Jammer grenades cause electomagnetic interference explosions. This interference has the following effects:
- Causes soldier implant timers to reset.
- Causes the following to cease functioning for a short time:
- Proximity Map radar.
- Vehicle weapons (except BFRs)
- Spitfire, Cerberus, Shadow, Phalanx, OMFT and manned Ancient Sentry Turrets.
- Motion Sensors and Sensor Disruptors.
- Causes High Explosive Mines, Disruptor Mines, and Boomers to detonate.
- Causes deployed Aegis Shield Generators and AMSes to temporarily decloak.
- Disrupts BFR systems:
- Slows servos for all frame movements
- Decreases weapon refire rate
- Disables Armor Siphon and NTU Siphon functionality
- Takes flight systems offline
- Slows shield regeneration significantly
In addition to the Hand grenade three-pack, Jammer grenades are also available in ammo boxes for use with the Thumper and Punisher.
